This is a multi-center clinical study enrolling up to 28 participants. The primary objectives are to determine the objective response rate (ORR) established by the confirmed best overall response (BOR) following intratumoral administration of DaRT - Diffusing Alpha-Emitters Radiation Therapy. Secondary objectives are to: 1. Determine Progression Free Survival (PFS) up to 12 months after Alpha DaRT sources insertion. 2. Assess Overall Survival (OS) of patients treated with DaRT up to 12 months. 3. Assess Local control up to 12 months after DaRT insertion.
This study is a multicenter, single arm, open label clinical study to assess the efficacy and safety of intratumoral Alpha DaRT-224 for the treatment of of Immunocompromised Patients with Cutaneous Squamous Cell Carcinoma The "Diffusing Alpha-emitter Radiation Therapy (DaRT)", based on the intratumoral placement of an encapsulated Radium-224 source (3.7 days half-life), is described in this study. These sources release short-lived alpha-emitting atoms into the tumor microenvironment by recoil. Alpha DaRT sources will be inserted into Cutaneous Squamous Cell Carcinoma tumors and will be remove…
